Not the greatest MCU movie, but it’s certainly watchable. Get past the VFX complaints, and the plot and storyline are actually pretty decent.
Interesting aspect of the multiverse concept, the ‘villain’ is in conflict with the ‘hero’ as well as with other versions of himself. Are those other versions also ‘villains’, or could some of them be ‘heroes’? Maybe in certain universes, Thor, for example, is a tyrant and Loki is the ‘hero’ - something to think about.
